Abstract

The invention relates to a medical pyretolysis patch, which comprises a backing layer, a gel layer and a protective layer, wherein the gel layer is arranged on the upper surface of the backing layer,the protective layer is arranged on the upper surface of the gel layer, the gel layer is a polymer gel, and the polymer gel is prepared from purified water, a gel assisting coupling agent, sodium polyacrylate, glycerol and temperature-sensing color-changing microcapsules. According to the invention, by adding the temperature-sensing color-changing micro-capsules to the gel layer of the medical pyretolysis patch, when temperature of medical pyretolysis patch exceeds about 38 DEG C, the temperature-sensing color-changing micro-capsules become colorless and the color of medical pyretolysis patchis pink, and when temperature of medical pyretolysis patch is lower than about 38 DEG C, the temperature-sensing color-changing micro-capsules turn back to dark blue and the color of medical pyretolysis patch is purple, so that a user can visually judge whether the user achieves pyretolysis effect based on the color of the medical pyretolysis patch.

Description

technical field [0001] The invention relates to the technical field of antipyretic patch, in particular to a medical antipyretic patch and a preparation method thereof. Background technique [0002] In daily life, people often encounter fever caused by various reasons, especially fever caused by exogenous factors. Timely physical cooling is the first measure to be taken. Physical cooling usually uses alcohol to rub the patient's back, face, abdomen, armpits, etc. The use of alcohol to cool down the temperature only has a single effect of cooling down and reducing fever, and cannot fundamentally eliminate the cause of the disease. In addition, antipyretic and analgesic drugs can be taken, but the drugs will bring very serious side effects to the human body, especially for pregnant women, babies and other special groups. Take antibiotics. [0003] Medical antipyretic patch is a physical cooling product, which is widely used in children with fever, summer and high temperature ...
